After the standards and learning outcomes have been identified,
your next step is to decide how students' mastery or understanding
will be assessed. For a short-term activity, this may consist of
observation, a quiz, or successful completion of a task. For long-term
activities, assessment should be on-going and may include measures
such as observations, quizzes, self-assessments, and performance
tasks.

Although assessment options will be discussed in more detail in
Lesson 5: Evaluation, it
is important to emphasize that they need to be addressed in all
phases -- beginning in the Decide phase. By examining how the outcomes
will be assessed in the beginning of a project, you can ensure that
the learning outcomes are appropriate and measurable. In addition,
it is important to provide students with a list of evaluation criteria
and standards for an activity at its onset. In that way, students
know what is expected of them.
